5x
5x squared plus 33x plus 18 = (5x + 3)(x + 6) x = -6, -3/5
(5x + 6)(x + 4)
x2 + 5x + not really sure what that extra plus is for... this is the most you can factor it... x(x + 5)
(x + 5)(x + 8)
You can factor a five out of 15 plus 5x. Therefore, 15 plus 5x factors out to 5(3+x). Hope it helps :)
15
5(x + 3)
(5x - 3)(3x + 5)

It is: 5x
30 + 5x = 15 + 10x 30 = 15 + 5x 15 = 5x x = 3
